### 3.5. OSPF Address Range Table

    --  Address Range Table

    --      The Address Range Table acts as an adjunct to the Area
    --      Table; It describes those Address Range Summaries that
    --      are configured to be propagated from an Area to reduce
    --      the amount of information about it which is known beyond
    --      its borders.
